Butter. I can't eat margarine now, knowing what I know. I grew up with margarine in the house, but I prefer the taste of butter anyway.

This. Exactly.

However, YDS is allergic to dairy, so we must use Earth Balance (soy free version whenever possible ). Still better than true margarine, it contains better things like coconut oil and the corn in it is non-gmo. It's vegan, so it's truly dairy free, unlike most margarines. Bonus: it doesn't taste plastic-y or coat your mouth like margarine does (we visited BIL and all they had was margarine... I was never more thankful for the dairy allergy! We *had* to go buy EB, "for JJ" )

Depends on what. I use butter in all cooking and baking, but to "butter" bread just to eat (like dinner rolls etc) I use margarine. I put margarine in my oatmeal um.. Yeah that's all I can think of that I use it for.

Something akong the lines of this minus the oatmeal part as I don't like it now.

Butter all the way...especially after I read somewhere that maragrine is 1 molecule away from being plastic

I'm a butter fan too, but this argument drives me bonkers. First, its internet lore and totally not true. Second, even if it were remotely true, a single molecule makes a huge difference. Water is h2o; hydrogen peroxide is h2o2. One molecule can turn water into something unsafe to drink, so should we stop drinking water?
